Eddy or Not: Do Eddies Actually Transport That Much Carbon? - Eos New data from remote floats around the world indicate the eddy subduction pump is of only secondary importance.

Carbon is transported deep into the ocean by a variety of mechanisms. New #AGUPubs research shows how much one of those mechanisms—the eddy subduction pump—matters.

New study @jgroceans.bsky.social uses a high-res transect and shows how the oceanic Transpolar Drift can be identified and how it affects conditions across the Amundsen and Nansen basins of the #Arctic Ocean, creating signficant constrasts in the conditions across the basins. #FramCentre #npolar

This was one of the 1st #AGU activities in China. Our students kept a panel of 5 editors up very late with a lot of questions about the publication process (we were answering until 21:30!). Some great audience questions to me representing @jgroceans.bsky.social :

AGU is now accepting applications for Editors-in-Chief across six publications, with terms starting Jan 1, 2027. These roles help shape editorial standards, research quality, and peer review in Earth & space science. Apply by May 1, 2026.

The 11th Geoscience Forum will attract about 5000 participants to Guangzhou in April 2026

For decades the USA was the main source of articles for #AGU journals. Now, for many journals China is the main country of origin. Yet editorial boards and outreach activities do not reflect this, so we are launching workshops across China starting with an Editor event at the 11th Geoscience Forum 🌊

💡Have you got an idea for a scientific workshop?

New in JGR Oceans Marine Snow Dynamics in the NE Gulf of Mexico: Particle Abundance, Characteristics, and Impacts on Deepwater Horizon Oil Sedimentation by Daly et al 2026

In a new study, scientists investigate the impact of the 2010 Deepwater Horizon on marine snow and evaluated seasonal marine snow dynamics in non-oil spill years (2011–2014).

It’s salty. It’s full of carbon. Its upwelling may have helped end the last ice age. It’s…the salty blob!

Bacteria Decide the Ocean’s Dissolved Organic Carbon Abundance - Eos Dissolved organic carbon prevalence follows from how many bacteria are around to eat it, modeling suggests.

It’s not what you have, it’s how you use it—even when it comes to the distribution of dissolved organic carbon in the ocean. The type of DOC is less important than how many bacteria are around to eat it, modeling suggests.

New in JGR: Oceans: Submesoscale Stirring Drives Lateral Dispersion and Vertical Exchange in a Cyclonic Mesoscale Eddy By Cao et al. 2026

Oceanic mesoscale eddies are often thought to have coherent structures that trap water in their cores.🌊

However, a new study shows that smaller-scale motions, known as submesoscale stirring, can disrupt this coherence.

A Mid-Ocean Ridge in the Norwegian Sea Pumps Out Hydrogen - Eos Vent fluids collected from the Knipovich Ridge contain unexpectedly high concentrations of hydrogen, potentially produced by the degradation of organic matter.

Hydrothermal hydrogen! 🫧 An ROV dive revealed high levels of molecular hydrogen in vent fluids ejected from a bubbly ridge in the Norwegian Sea. 🧪
